The CM6000 hydraulic breaker (manufactured by McQuaid Engineering) was commissioned at Galmoy mine in September 2008. The unit has been in operation on a 24/7 shift rota, it's primary duty is to break zinc and lead ore down to a manageable size to enter the operational jaw crusher.

Jul 02, 2020· Jul 02, 2020· Maintenance went to switch a 70A breaker that tripped which caused the breaker. We know the 70A breaker tripped because of a ground fault when we found some wire with no insulation on it. My question is that between the 70a and main breaker, there were two smaller breakers. One was for the full panel that the 70A breaker is.
